NETTING.

SPECIFICATION forming part of Letters Patent No. 621,891, dated March28, 1899.

Application filed January 18, I899. Serial No. 702,535. (No'modelJ T0aZZ whom it mag concern:

Be it known that I, IVERS S. ADAMS, of Cambridge, county of MiddleseX,and State of Massachusetts, have invented an Improvement in Netting, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

The present invention relates to a netting or similar structure havingthe strands thereof connected together at intervals, and is mainlyembodied in a novel arrangement of the strands to form theconnecting-knot, the object of the invention being to prevent theslipping of one strand with relation to another, which is liable tooccur when the meshes of the net are stretched. In such netting as nowcommonly made the strands are usually connected by means of the ordinaryweavers knot, and pressure on the strands is liable to cause the loop ofthe knot to pull through, so that the knot slips and widens the mesh.

The material embodying the invention is mainly used for fish-nets, andwhen strands are connected by means of the weavers knot a large andpowerful-fish will frequently press against the strands in such a way asto cause the loop to pull through and the knot to slip, so that the meshwidens sufficiently to let the fish escape. In netting constructedaccord ing to this invention the formation of the knot is such as toeffectually prevent the slipping of the strands and consequent wideningof the meshes.

Figure l is an enlarged view of two strands at the point where they arefastened together, showing the relation of the said strands to eachother when the knot is formed; and Fig. 3 is a View on a smaller scale,showing one mesh of netting or like structure to illustrate more fullythe manner in which 'the strands are arranged and knotted together.

The material embodying the invention comprises two sets of strands C6and b, which alternate along the fabric, as indicated in Fig. 2, eachstrand (1 extending along the material in a zigzag direction and beingconnected first with a strand 1) at one side and then with anotherstrand 1) at the opposite side, the strand 1) being arranged in the sameway with relation to the strand a. The knot is formed in accordance withthe present invention by forming simple loops in each strand of one setat each point of connection, the said loops being herein shown as formedin the strands a, the two ends crossing each other and forming what maybe described as the upper member a and lower member a of the loop. Thestrand b in accordance with the invention is shown, Fig. 1, as passingin through the loop above the uppermember a and then below the lowermember a and after it is thus passed through it is wound around the saidlower member beyond the loop, then passing over the said upper memberand out through the loop in the opposite direction-that is to say, belowthe member a as shown. The said strand 1) is thus formed in a kind oftwisted loop 11 the ends of which cross each other and pass through theloop a a in opposite directions.

It is to be understood, of course, that the terms above and below areused merely for convenience and refer to the knot when it is in theposition shown in the drawings, it being obvious that the knot will bethe same regardless of the position in which the fabric is placed, thetwo strands always having the same relation to each other. Comparing,for example, the different knots shown in Fig. 2 it will be seen thatthe up per member of the loop in the strand a in the knot shown in theupper part of the drawings is continuous with the lower member of thesimilar loop in the knot shown at the right-hand side of the drawings,but that the In testimony whereof I have signed my name to thisspecification in the presence of 10 two subscribing witnesses.
